AMS Short Course on Phased Array Radar Polarimetry

15 September 2013, Breckenridge, CO

This afternoon, half-day workshop will provide background of radar polarimetry and phased array technology, to highlight issues that need to be considered, and to introduce recent advancements and applications to the weather community.

Drs. G. Zhang and R. J. Doviak will present and discuss recent advancements in weather radar development and applications.  Radar polarimetry with multi-parameter measurements has matured to the point that it is being implemented on the national network of WSR-88D Doppler radars. Phased array technology has recently been introduced to the weather community to increase data update rates to lengthen the lead time of weather hazard warnings. Polarimetric phased array radar is desirable for future weather observations, but there are significant issues and challenges to retain quantitative measurements. This short course will provide the background information on Polarimetric Phased Array Radar (PPAR) and its applications, and will introduce the latest advances in research and development of a PPAR that can serve the multiple functions (e.g., weather and aircraft surveillance).

Beside fundamentals and principles for radar polarimetry covered in the presentations, students will also gain hand-on experience in understanding polarimetric radar measurements through model calculation/simulation of wave scattering by hydrometeors. Sample Matlab codes, rain drop size distribution (DSD), and polarimetric radar data will be provided for student’s learning and practice. It is expected that students will be able to simulate and analyze polarimetric radar data, and to study cloud and precipitation microphysics through hydrometeor classification and DSD retrieval. It is requested that each participant bring their own laptop with Matlab for the exercise.
